STORM on sonnen sasn FASTENER.

To all 'whomit may'concem:

Be it known that I, JAMES G. RALPH, of Aurora, in the county of Kane andin the State of Illinois, have invented a certain new and usefulImprovement in Storm or Screen Sash Fasteners, and do hereby declarethat the followingr is a full, clear, and exact description thereof,reference being had to the accompanying drawings, in which- Figure 1 isa front elevation showing a window provided with my fastening means forsash or scret ns; Fig. 2 is a vertical section of the same; Fig. 3 is aperspective view of the button, and Fig. 4 a detail view of a differentform of rod-engaging pin.

My invention relates' to fastening means for removable sash or screensfor windows, etc., and my object is to provide a simple, easily operatedand efficient fastening 'which will mos't firmly and securely hold thesash or other part in place, and to this end my invention consists inthe construction substantially as hereinafter specified and claimed.

To illustrate one application of my invention, I show in the drawings awindow frame A, of ordinary construction, having, as usual, a blind stopB. Yithin the frame, outside the blind stop, are an upper sash C and alower sash D, which are removablysecured in place. Confining thedescription to the lower sash, it is provided at its upper end withfastening means consisting of a hook d on the top rail of the sash ateach side thereof, and a in ay on the window frame to cooperate with tie hook, on which hook and pin device the sash may beswung outward atthe bottom into the position shown in dotted lines in Fig. 2, forpurposes of ventilation. On the lower rail b of the sash, at the innerside thereof, I pivot a latch device in the form of a turn button Ewhich consists of a cylin- -drical body part and a flange e on the outerend of the body part, whose surface next the'- sash is inclined like thesection of a screw thread to co-act 'with a vertical pin F project ingfrom the .vindowsillG, the cam flange, by the turn of the button beingmovable into and out of engagement with the pin, and

when moved in the direction to engage the Specification of LettersPatent. y Application le August 18, 1906. Serial No. 331,201.

pin coacts with the latter to draw the sash inward against the blindstop, and thus firmly holds the sash in position.

To limit the rotary movement of the turn button in a sash-securingoperation, there is a lug or rib e that stands parallel with the axis ofrot-ation of the button, which, by striking the pin will arrest furthermovement of the turn button.

The location of the turn button and the position of the fiange are suchthat when the. utton is in a locking position the mass of the turnbutton is below its center of rotation,

so that any shaking or jarrinup of the sash, as

by the action of heavy win will have no tendency to jar the turn buttonout of loclting position. or rotating the turn but-ton, the body thereofis provided diametrically opposite the flange with a radial arm or hande cl2, and such handle is situated on the outer end of the turn buttonbody, so that when the sash is moved into position fol` locking, shouldsuch handle be uppermost, it will, when the turn button is rotaterreadily pass the in on the sill. In addit.on to -the said han' le, a ribor lug e3 is provided on the outer side of the flange, diametrically oposit-e the handle, for use in turning tie utton.

T he turn button is complete as I have shown 1t, but I may use, mconnection with it, a rod. G', which is pivotally connected at one endto the handle d, and at its other end has an eye g which, when the sashis swung into the osition shown in dottec-` lines, may be placed) inengagement with the pin F on the sill to sup )ort the sash in suchposition. If preferred, t ie pin F, as shown in Fig. 4, may have 'an eyef to engage a hook on thc rod G; and this form of pin is useful where asash hinged at the bottom is used and the in is in the head of thewindow frame and not the sill.V Although I have used the term sash in mydescription, because I have shown in the drawings a windev: havingglazed sash, it is to be understood that I do not restrict myself to theuse of my fastening means to any particular window or door structure.

Having thus described my invention, what I 'claim is:;

In a window or like oonstruetion, the combnation of a. frame, e membermounted to 5 swing in the frame, a turn button on said member, a pin forcoperation with the turn button secured to the frame, and a rodconnected with the turn button and adapted to engage said pin when themember is swung to an open position, to hold the same therein. 10

In testimony that I claim the foregoing I have hereunto set my hand. 1
